ABSTRACT:
A liner for lining the interior of subterranean pipes, such as sewers is formed from a seamless, knitted fabric sleeve having a pile construction in which piles extend away from a ground portion of the sleeve, open areas being formed among the ground and piles. A synthetic resin is applied to the fabric sleeve so as to thoroughly impregnate the sleeve. The resin-coated sleeve may be installed in an underground pipe by everting same under fluid pressure. The sleeve has expansion capabilities which permits the resin-impregnated sleeve to be in contact with the interior surface of the pipe for the entire length of the sleeve.
